A joint assembly comprising at least one extruded profile member and at least one molded member connected to the profile member by an injection molding process. The extruded profile member comprises at least one pre-processed structured surface area adapted to increase grip between the profile member and a molding tool during the molding process. A method for forming a joint assembly is also disclosed, comprising the steps of comprising: inserting an extruded profile member in a molding tool, the extruded profile member and/or the molding tool having a structured surface area to increase the friction between the molding tool and the extruded profile member; clamping the molding tool and bringing the structured surface in contact with the molding tool and/or the extruded profile member to hold the profile member in place, and injecting material into the molding tool to produce a molded member connected with the extruded profile member.

A diffuser assembly includes a flexible diffuser membrane and a diffuser body. The flexible diffuser membrane defines a circumferential bead. The diffuser body defines a circular plate underlying the flexible diffuser membrane, and an edge ring covering a covered portion of the circumferential bead. The edge ring defines an inside surface that conforms to an outside shape of the covered portion of the circumferential bead. The edge ring is integral to the diffuser body. Such a diffuser assembly may provide a disposable diffuser assembly option with many advantages over conventional technologies such as improved ease of installation, lower weight, and lower cost.

The disclosure discloses a vehicle interior panel for covering an airbag and a method of fabricating a vehicle interior panel for covering an airbag. The vehicle interior panel includes a substrate with an opening, a chute channel assembly inserted into the opening, a surface skin, and a foam layer disposed between the surface skin and the substrate. The chute channel assembly includes a wall section surrounding a chute channel for the airbag and a cover plate covering the chute channel and closing the opening. The cover plate includes an airbag door, wherein an outer surface of the cover plate is in contact with the foam layer. The outer surface of the cover plate has a rough surface structure, the outer surface having a surface roughness parameter R.sub.a of at least 4 m.

There is disclosed a method of manufacturing an in-mold labelled article, the method comprising the steps of: placing a label comprising a film having a core comprising polypropylene/polyethylene random copolymer as its principal polymeric constituent into a mold for injection molding, thermoforming, or blow molding; holding the label in position; injecting a polymeric melt into, or thermoforming or blowing a polymeric preform in said mold so as to bind with the label; and removing the article from the mold. A process of in-mold labelling using such a label is also disclosed.

A polymer molded article including: a base portion; and a surface layer portion thermally bonded onto the base portion, wherein the polymer molded article satisfies the following requirements: 1) Gs>Gb where Gs is a rigidity of the surface layer portion, and Gb is a rigidity of the base portion; and 2) Tms<Tp where Tms is a melting point of the surface layer portion at a joint portion with the base portion, and Tp is a molding temperature during the thermally bonding.
